Product details

Mounting and environmental fit

Dimensions are 150 mm deep × 110 mm wide × 230 mm high. Screw fixing (not DIN-rail snap-on) means it mounts directly to a backplate or machine frame — plan for four drilled holes and M5 hardware. Shock resistance of 15 g / 11 ms and vibration resistance of 2 g mean it survives the mechanical stress of a conveyor line, a press, or a packaging machine without loosening internal connections. Mounting position can be vertical or horizontal, giving flexibility in tight cabinets.

No second-source cross-reference exists within the SIMATIC family that matches the reversing, IP65, PROFINET feature set identically.

Frequently asked questions

What is the SCCR of 3RK1304-5LS40-3AA0?

The short-circuit current rating is 100 000 A at 400 V AC, which allows placement on high-fault bus systems without additional current-limiting protection.

How do I get current pricing and availability for 3RK1304-5LS40-3AA0?

This part is sourced through independent distribution. Submit an RFQ for current pricing and availability — both are confirmed at quote time.

What is the depth of 3RK1304-5LS40-3AA0?

The depth is 150 mm. Overall dimensions are 150 mm deep × 110 mm wide × 230 mm high.

What compliance documentation does Siemens provide for this motor starter?

As a current-production SIMATIC component, Siemens provides a Declaration of Conformity covering the applicable EU directives (EMC, Low Voltage, RoHS). The IP65 rating and pollution degree 3 are tested per IEC 60529 and IEC 60664-1 respectively. Specific UL/CSA file numbers are available in the product certificate on the Siemens support portal.
